Greek scholar of wide interests who is best known for his Chronika (Chronicle) of Greek history. Apollodorus was a colleague of the Homeric scholar Aristarchus Of Samothrace (both served as librarians of the great library in Alexandria (Alexandria, Library of), Egypt). Apollodorus left Alexandria about 146 for Pergamum and eventually settled at Athens. The Chronicle, written in the iambic trimeter used in Greek comedy, covers the period from the fall of Troy (1184 BC) to 144 BC in three books and was later continued to 119 BC in a fourth book.

Apollodorus's publications extended to philology, geography, and mythology. He wrote commentaries (in at least 4 books) on the Sicilian author of mimes Sophron (Sophron Of Syracuse) and (in 10 books) on the playwright Epicharmus, as well as a work that consisted of glosses explaining rare words. Much of his 12-book commentary on the “Catalogue of Ships” in Book II of Homer's Iliad survives in the work of the ancient geographer Strabo (Geography, Books VIII–X). His work Peri theōn (On the Gods), in 24 books, was scholarly in character and influenced the Epicurean Philodemus. A compendium to Greek mythology, called Bibliothēke (often Latinized as Bibliotheca; The Library), extant under his name, is in fact not by him but was composed in the 1st or 2nd century AD, as was a (lost) guidebook in comic trimeters, A Map of the Earth.
